Hey Trail Momma -
I am in the East Bay and don't mind commuting a bit on a weekend for a nice run. I typically run streets/dirt bay and lake trails (so, flat) but I do really enjoy trail running. If you're interested in arranging a run sometime, either post a message here, or email me at katiestewart444@hotmail.com.
I'm a slower runner, and am also now 15 weeks pregnant, so am slowing down more and more. I saw your post in the trail running section - the speed looks about right to me, but I haven't run more than 8 miles in several months, so I couldn't do real long runs, but could meet you for part of a longer run, or, depending on the training schedule you settle on, a shorter recovery run or something.
